示例1: releaseTimerId
void QAbstractEventDispatcherPrivate::releaseTimerId(int timerId)
{
int which = timerId & 0x00ffffff;
int bucket = bucketOffset(which);
int at = bucketIndex(bucket, which);
int *b = timerIds[bucket];
int freeId, newTimerId;
do {
freeId = nextFreeTimerId;
b[at] = freeId & 0x00ffffff;
newTimerId = prepareNewValueWithSerialNumber(freeId, timerId);
} while (!nextFreeTimerId.testAndSetRelease(freeId, newTimerId));
}示例2: releaseTimerId
// Releasing a timer ID requires putting the current ID back in the vector;
// we do it by setting:
// X[timerId] = nextFreeTimerId;
// then we update nextFreeTimerId to the timer we've just released
//
// The extra code in allocateTimerId and releaseTimerId are ABA prevention
// and bucket memory. The buckets are simply to make sure we allocate only
// the necessary number of timers. See above.
//
// ABA prevention simply adds a value to 7 of the top 8 bits when resetting
// nextFreeTimerId.
void QAbstractEventDispatcherPrivate::releaseTimerId(int timerId)
{
int which = timerId & TimerIdMask;
int bucket = bucketOffset(which);
int at = bucketIndex(bucket, which);
int *b = timerIds[bucket];
Q_ASSERT_X(timerId == -b[at], "QAbstractEventDispatcher::releaseTimerId",
"Internal error: timer ID not found");
int freeId, newTimerId;
do {
freeId = nextFreeTimerId;//.loadAcquire(); // ### FIXME Proper memory ordering semantics
b[at] = freeId & TimerIdMask;
newTimerId = prepareNewValueWithSerialNumber(freeId, timerId);
} while (!nextFreeTimerId.testAndSetRelease(freeId, newTimerId));
